Product sounds: Basic concepts and categories

In this paper we investigated which categories of product sounds listeners can distinguish. We explored the perceptual domain of product sounds in order to be able to derive perceptually similar categories and determine how users are able to describe these categories by merely listening to them. Employing two different experimental paradigms ...

Auditory signal design for automatic number plate recognition system

This paper focuses on the design of an auditory signal for the Automatic Number Plate Recognition system of Dutch national police. The auditory signal is designed to alert police officers of suspicious cars in their proximity, communicating priority level and location of the suspicious car and taking into account the auditory environment of the...

Roughness vs. contrast in natural textures

We investigate the effect of contrast enhancement on the subjective roughness of visual textures. Our analysis is based on subjective experiments with seventeen images from the CUReT database in three variants: original, synthesized textures, and contrast-enhanced synthesized textures. In Experiment 1, participants were asked to adjust the...

Transitional Journey Maps: Capturing the dynamics of operational policing

Operational police work can be characterized by the continuous switching between surveillance, responding to incidents, and office activities. Transitions between these activities are initiated by radio contact, messages on a mobile data terminal, or personal observations. The “information environment” emerging from these channels may cause...

Product Sound Design: Intentional and Consequential Sounds

Sound meets image: Freedom of expression in texture description

The use of sound was explored as means for expressing perceptual attributes of visual textures. Two sets of 17 visual textures were prepared: one set taken from the CUReT database1, and one set synthesized to replicate the former set. Participants were instructed to match a sound texture with a visual texture displayed onscreen. A modified...

Basic semantics of product sounds

Product experience is a result of sensory and semantic experiences with product properties. In this paper, we focus on the semantic attributes of product sounds and explore the basic components for product sound related semantics using a semantic differential paradigmand factor analysis. With two experiments, we determined eight factors that...

Subband analysis and synthesis of real-world textures for objective and subjective determination of roughness

In a previous study we investigated the roughness of real world textures taken from the CUReT database. We showed that people could systematically judge the subjective roughness of these textures. However, we did not determine which objective factors relate to these perceptual judgments of roughness. In the present study we take the first step...

Audio-visual interactions in product sound design

Consistent product experience requires congruity between product properties such as visual appearance and sound. Therefore, for designing appropriate product sounds by manipulating their spectral-temporal structure, product sounds should preferably not be considered in isolation but as an integral part of the main product concept. Because visual...

Roughness in sound and vision

In three experiments the perceived roughness of visual and of auditory materials was investigated. In Experiment 1, the roughness of frequency-modulated tones was determined using a paired-comparison paradigm. It was found that using this paradigm similar results in comparison to literature were found. In Experiment 2, the perceived visual...

Impact of sound on image-evoked emotions

In two experiments the effect of sound on visual information was investigated. In Experiment 1 the effect of the visual appearance of product types with an expensive deign and with an inexpensive design on the experience of the sound recordings of these products was investigated. Recordings and pictures were systematically interchanged. Thus,...
